Potter CSS CoilKeeper Supervisory Switch (1010500)

Protect your preaction or deluge system with dependable coil supervision. The Potter Electric Signal CoilKeeper Supervisory Switch is a wired supervisory device that continuously monitors solenoid coil position to meet NFPA 13 requirements, preventing accidental disconnection or unintended releases. The CSS (Model CSS, P/N 1010500) electronically detects coil presence and faults—open or shorted coils—and activates a normally open dry contact for direct connection to releasing control panels and supervisory circuits. Built-in LEDs provide clear status and troubleshooting indicators, and the unit can be mounted at the solenoid or remotely for flexible installation in mechanical rooms or security enclosures. Designed for water flow controls, the CoilKeeper supports integrated security and monitoring workflows, helping facilities maintain compliance and minimize false activations. For installers and specifiers focused on reliable surveillance and system integrity, the Potter CoilKeeper streamlines diagnostics and reduces service calls.
